Gravity: I2C Non-contact IR Temperature Sensor For Arduino (MLX90614-DCC)
All prices are VAT included
In recent years non-contact measurement methods have been used for medical, environmental monitoring, home automation, automotive electronics, aerospace, and military applications.
Our latest infrared temperature measurement module is the MLX90614. This module measures the surface temperature by detecting infrared radiation energy and wavelength distribution. The IR temperature probe consists of an optical system, photoelectric detector, amplifier, signal processing, and output module. The optical system collects the infrared radiation in its field of view and the infrared radiation energy is converted into to corresponding electrical signals when converging on the photoelectric detector. After being processed by the amplifier and signal processing circuit, the signal is converted to a temperature value. The MLX90614 is self calibrating and has a low noise amplifier integrated into the signal processing chip. The chip itself is a 17 bit ADC and DSP device, giving accurate and reliable results.
Note: The MLX90614 offers a standard accuracy of ±0.5˚C around room temperatures, while the medical-grade MLX90614 offers an accuracy of ±0.2˚C in a limited temperature range around the human body temperature.
Gravity: I2C Non-contact IR Temperature Sensor For Arduino (MLX90614-DCC) , due to its large field of view (FOV = 35°), is more suitable for commercial application. We recommend Gravity: I2C Non-contact IR Temperature Sensor (MLX90614-DCI) for industrial applications. It has a longer distance range.
